Aumund supplies cleaning and sorting conveyor to Hawle

Aumund Fördertechnik in Rheinberg offers reliable and cost-effective transportation and conveying solutions for foundries all over the world. After having supplied a flat plate conveyor to replace a vibratory feeder in the summer of 2021, Aumund has now developed a special cleaning and sorting conveyor for Hawle Guss in Fürstenwalde, which was commissioned in 2022.

Modern cleaning and conveying technology

Hawle Guss in Fürstenwalde is a major manufacturer of products for gas and water distribution systems, such as taps, hydrants and valves. Hawle Guss requires the appropriate conveying technology for its new concept for degating, sorting and cleaning of castings at the foundry.

The function of the conveyor supplied in 2021 by Aumund is purely to transport material from the manufacturing plant in the basement on to the next process stage on the ground floor. In August 2022, as part of the next stage of expansion, a cleaning and sorting Conveyor was commissioned. This Conveyor had been specially developed for the application, and replaced the previously utilised vibrating conveyor.

Tailor-made solution

The metallurgy specialists at Aumund Fördertechnik based the project on a particular Aumund product which had been supplied to foundries decades ago, and of which only a few photos and not a single drawing remained. Aumund and the customer worked closely together to come up with the concept for a tailor-made solution which resulted in the development of a completely new Cleaning and Sorting Conveyor with an overall length of 11.45 m and an operational area of 8 m.

Clear advantages

The previous heavy exposure to noise and vibration was almost completely eliminated. The consequences of this transformation are a considerable improvement in working conditions and at the same time a reduction in energy consumption. The flat surface provides a comfortable working height for sorting and cleaning the castings without danger of obstruction. The design of the conveyor plates was optimised to avoid any cracks at the edges, and to enable the castings to be ejected sideways. At the same time a degree of mechanical stability could be achieved which is sufficient to enable operation with a manipulator. Because of the high tensile  strength of the plates, impact loads of up to approx. 2.5 t can be tolerated without causing any deformations. The Conveyor was designed in such a way that all key structural components could be housed internally. With vibratory technology and hydraulic components no longer required, all advantages of a simple and reliable mechanical conveying equipment are at the forefront.
